DIE FOR USE IN MAKING BARBED FENCING.

SPECIFICATION forming part of Letters Patent No. 450,046, dated April 7, 1891. A v

Application filed July 30,1888. Serial No. 281,411. (No model.)

T0 at whom it may concern.-

Be it known that I, J osnrn H. TEMPLIN, a citizen of the United States, and aresident of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in a Combination of Fencing, of which the following is a specification.

This invention consists of improved contrivances of dies for producing two barbed strips from a double blank strip by slitting the strip along the middle by two different ranges of short slits made successively, which are in two parallel lines and two diagonal lines connecting the parallel lines, and the other that the diagonal lines of one slit cross the diagonal lines of the other slit and cut the points of the barbs, while the parallel lines extend therefrom each way the length of the barbs and out both edges of the body portion of them from the strips and complete or partly complete the separation; and the invention also consists of suitable bending-dies, combined with theslitting-diesthus contrived, for bending the barbs to produce the required lateral projection, and also dies for trimming off slight points left on the edges of the strips by the slitting-dies, all as follows, referring to the drawings, in which-- Figure 1 represents a face views of the slitting and bending dies. Fig. 2 represents a side elevation of the same with the blank strip between them. Fig. 3 is a diagram of the. blank strip, showing the action of the dies on it. Fig. 4 represents face views of the slitting and bending dies with other dies for trimming off the points left on the strips by the slitting-dies between the diagonal cuts. Fig. 5 is a diagram of the blank strip, showing the action of the dies of Fig. 4 on it. Fig. 6 represents face views of a modified arrangement of slitting-dies together with bendingdies and point-trimming dies. Fig. 7 is a diagram of the blank strip, showing the action of the dies of Fig. 6 on it.

One range of slits, and preferably the one first made in the blank strips a, consists of the two short slits ab, one a little in advance of the other, which slits are partly invtwo different parallel lines as wide apart as the width'of the barbs to be made and partly in the diagonal lines connecting the parallel lines, said diagonals being inclined reversely to each other and the two contiguous ends of the slits being in one line and the opposite ends of said slits in another of the parallel lines with the uncut web a between the ends of the slits. These slits are repeated successively at intervals apart, leaving the uncut webs f. For the making of them I employ two pairs of dies 0 p, placed side by side and a little apart, which dies have the cutting-edges d in parallel lines and c in diagonal lines connecting lines 01, the diagonals being reverse to each other in their inclination, and the length of the dies being about the length of two barbs to be made. They are preferably arranged so as to Work independently of each other; but the upper dies may be formed together on one stock and the two lower ones together on another stock, and may work together. The other range of slits is represented by the continuous slit g, of like character and preferably longer than slits a I) combined, and being reversed thereto, so that its extremities are in theline of the contiguous ends of slits ab, and its diagonals cross thoseof slits a b, the length being equal to the length of the feed movements of the strip, so that they connect successively at h, and with the slits a I) out four barbs e at once and separate the barbstrips 2' 3', two of which barbs are joined to one barb-strip j by web 0, left between the contiguous extremities of slits a Z), and two others are joined to barbed strip 11 by uncut webs f, left between the opposite extremities of said slits, the former by reason of the distance of cutters a b apart and the latter through the feeding of the blank as much more at each movement than the length of said slits as is required for reserving said retaining-webs. The slits g are made by the dies 7t Z, having cutting-edgesformed partly in parallel lines (1' d and diagonal lines a, similar to the lines of dies (1 1), except as to being reversed and continuous and longer, as before stated, and they are suitably located in range with dies a b to act successively to them 011 the blank which feeds intermittingly a length equal to the length of dies kl at each movement. Next following these dies are two pairs of benders m n for bending the barbs for the lateral projection, one pair for each couple of barbs. They consist of a suitable male and female contrivance for so bending them by the one it in the form of a punch thrusting through the blank and bending the barbs into the other m, suitably recessed for allowing the barbs to be bent into it, and they are arranged for bending in opposite directions for the alternate opposite projection of the barbs. The slight points q left on the edges of the strips by the crossing diagonal cuts may be allowed to remain, the punches at being suitably grooved in' the sides, as represented in Figs. 1 and 2, for bending the barbs without disturbing said points; or the. bending-dies maybe contrived for cutting them off 'as well as for bending the barbs; but I prefer to provide other dies for the purpose-for instance, a punch, as s, which with its proper counterpart will make slits t, or as it, which will also make slits t, that being made before the slits (6 b or g are made-and so gaged' that the diagonal cuts come together with them, as in Figs. 5 and 7, they will trim off the points q; but instead of making these slits in advance of the others they may be made later, as between the making of the slits g and the bending of the barbs or after the bending.

If desired, two pairs or" dies 7a Z, of the form and dimensions as dies 0 17, may be employed in lieu of the dies 70 Z, together with others as to make slits, as y, for cutting where they would come short of completion at y y, this beingamodification which is practically the same as the others and accomplishes the same results. The dies 00 may, like the dies 8 a, be located in the range so as to work successively to the others. It is obvious that the dies 0 p and 71'; lmay be reversed asto their order of arrangement in the range, so that the slits 9 will be made first and a 1) next.

The method or process herein described is reserved for a separate application for a patent.

WhatI claim, and desire to secure by Letters Patent, is

1. The combination of two pairs of dies 0 13, having cutting-edges in two parallel lines,

as cl d, and a diagonal line, as 0', connecting the parallel lines,and dies, as 7t Z, also having cutting-edges in two parallel lines, as d d, and diagonal lines, as c 0', connecting the parallel lines in a range, and in the reverse arrangement of the diagonal edges, making two ranges of slits, whereof the diagonal lines of the slits of one range cross the diagonal lines of the slits of the other range and cut the points of the barbs, while the parallel lines extend therefrom each way the length of the barbs and out both edges of the body portions of them from the strips and complete the barbs and partly or wholly complete the separation of them, substantially as described.

2. The combination of two pairs of dies, as

013, having cutting-edges in two parallel lines, as d d, and a diagonal line, as 0, connecting the parallel lines, and dies 70 Z, also having cutting-edges in two parallel lines, as cl (1, and diagonal lines, as 0, connecting the parallel lines in a range, and in the reverse arrangement of the diagonal edges, making two ranges of slits, whereof the diagonal lines of one range cross the diagonal lines of the other range, and also two pairs of bending-dies, as n on, also in range with the cutting-dies and adapted to bend the barbs out by said dies laterally to the strips, substantially as described.

3. The combination of two pairs of dies, as o 19, having cutting-edges in two parallel lines, as d cl, and a diagonal line, as 0, connecting the parallel lines, and dies, as 70 Z, also having cutting-edges in two parallel lines, as d d, and diagonal lines, as c 0, connecting the parallel lines in a range and in the reverse arrangement ofthe diagonal edges, making two ranges of slits, whereof the diagonal lines of one range cross the diagonal lines of the other range, and also point-trimming dies, as s or u, also in range with the cutting-dies, and adapted to trim off the points remaining between the diagonal cuts, substantially as described.

Signed at New York city, in the county and State of New York, this 2d day of May A. D. 1888.
